Encrypting and compressing zFS file system data

New zFS file system data can be encrypted and compressed. The file system can be defined and formatted so that any data added to them is automatically encrypted, compressed, or both. After a file system is encrypted or compressed, additional new entries will also be encrypted or compressed. Use format_encryption=on or format_compression=on in your IOEFSPRM configuration file if you want data in all new zFS file systems to be automatically encrypted, compressed, or both. The default for both is off.

Existing zFS file system data can be encrypted and compressed. Encrypting or compressing an existing file system is a long-running administrative command. Operator messages are issued during the operation, and the progress of the operation can be monitored with FSINFO. During this process, background tasks on the zFS owning system will process every object in the file system. Application access is fully allowed to the file system during the operation.
